l 'o all wlw/m, t may concern.'

Be it known that I, JACOB J. SMITH, a citizen of the United States, anda resident ol" the city of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful improvements in Oil-GasGenerators and Burners; and I do hereby declare that the following is afull, clear, and exact description or' the same, reiference being had tothe accompanying drawings, and to the numerals of reference markedthereon, which form a part of this specification.

rlhis invention pertains to an improved type of an oil-gas generator andburner wherein the oil supply pipe is inclined downwardly toward itsentrance end to permit the saine to drain toward the supply and preventimpurities or carbonrom entering the carbureting parts oit the device.The inclined supply pipe also serves as an oil vaporizing means which isiirst heated by a starting burner and afterward by a generating burnerto generate an oil vapor adapted to be carbureted with air to `form anoilgas. T he generated oil-gas is admitted into a storage tank to beused as a i'uel in said generating burner to perpetuate the process ofoil-gas generation and is turthernioreused as a fuel to burn in cookingburners which are integrally formed on said storage tank.

It is an object of this invention to construct an oil-gas generatorhaving an oil supply and generating pipe inclined toward the inlet endto prevent carbonization of the generator parts.

Another object of the invention is the construction oi' an oil-gasgenerator' and burner wherein the cooking burners are integrally formedon the oil-gas storage tank.

It is also an object of the invention to provide an oil-gas generator'and burner having an inclined oil supply and generat- .ing pipe adaptedto be initially heated by a wick starting burner provided with an underfeed.

It is a further object of this invention to construct an oil-gasgenerator and burner wherein oil is heated and vaporized and thencarbureted with air to forni an oil-gas :t'uel adapted for use incooking burners and in a generating burner for the purpose of continuingthe process of oil-gas `Generation.

It is an important object oi the invention to provide a generatingburner of simple construction wherein kerosene oil is first volatilizedby a starting or a generating burner and is then admitted into acarbureter to permit air to be carbureted there with to form an oil-gas.

@ther and further important objects of this invention will be apparentfrom the disclosures in the speciiication and d 1awings.

The invention (in a preferred form) is illustrated in the drawings andhereinafter more fully described.

As shown on the drawings:

The reference numeral l, indicates a'large casing, gas reservoir or gasstorage tank` provided with an aperture or opening 2, in the front wallthereof, surrounded by an outwardly projecting collar S. integrallyformed on the top or each end of: the casing l, is a cooking burnercomprising a burner box 4, having a plurality of burner or gas openingsor apertures 5, formed in the top wall or plate thereof. The uppercorners of each of the burner boxes l, are notched, as denoted by thereference numeral 6, to permit baie plates to be mounted upon the burnerboxes it desired. ntegrally formed on the bottom and at one end of thecasing` l, and in communication with the interior thereof, is smaller orauxiliary gas casing 7, provided with an inlet opening S, in the' outerend wall thereof, ttor a purpose hereinafter described. Formeel withinthe casing l, and .separating the interior thereof from the interior ofthe auxiliary casing T, is a partition or wall Sly-constructed to lezlVe an opening l0, to permit gas from the auxiliary casing to passupwardly into the main or upper casing 1.

Rigidly secured to the back of the casing 1, are the upper ends of anglesupports or legs 11, the horizontal positions of which serve as feet.Disposed longitudinally in front of the auxiliary casing and extendingbeyond the ends thereof is a. fuel iniziing or carbureting pipe 12, oneend of which is curved to form an elbow 13, having integrally formed onthe inturned end thereof a flange rim or ring lll, which is rigidlysecured to trie outer end wall of the auxiliary casing Y, to registerwith the inlet opening 8.

tiecured or projecting into the collar 3, of the main gas casing l, isone end of a stub pipe or neck l59 on the outer end of which isintegrally formed or rigidly secured a generating burner disposed infront of the casing 1, and comprising a main pipe 16, of squared orangular cross-section and inclined with respect to the horizontal. Theouter end portion Vof the pipe 1G, is turned vertically downwardly toforni a branch pipe 17.

of said generating burner is provided with a plurality of burnerapertures or openings 13. The 'front wall of the branch pipe 17, is alsoprovided with a. plurality7 of apertures or openings 19, disposedtransversely across said branch pipe near the lower end thereof. Formedat the bent portion or at the elbow of the generating burner is aprojection 20, on the end or which is secured a supporting or retaininglatch 21,

The projecting finger or free end of the latch 2l., engages and supportsthe downwardly jnfojecting discharge arni 2Q, integrally formed on thehigher end of a long oil. supply or oil-gas generating pipe or tube 23,which is disposed directly in front of the generating burner and isinclined downwardly toward the inlet end 9st, thereof. The inlet arm isdirected downwardly and is connected by ineans of a feed or supply pipe25, with a kerosene or oil supply tank, not shown. of the generatingburner 16, is a bracket 0r arm 26, which engages underneath the inclinedgenerating pipe 23, to help support the saine in position.

rfhe discharge arm is disposed in front of the branch generating burnerpipe 17, and together therewith project into a box or shield 2T, open atthe top and at the outer -end, an@L attached to the rear of thegenerating burner by screws or bolts 23. The shield 27, is positionedadjacent the open lower end of the carbureting pipe 12, and

Both ends of the generating burner a are closed, and the front surfaceor wall Secured to the inner endthe end wall of said shield is providedwith an opening disposed directly opposite the open end of saidcarbureting pipe.

Associated with the lower end of the discharge arm 22, and projecting`longitudinally through the shield Q7, is a needle valve mechanism forcontrolling the flow of heated Va-porized oil from the generating pipe23, into the carbureting pipe 12. rlhe Valve mechanism embraces a shortpipe or tube 29, integrally formed at right angles to the lower portionof the discharge arm 22, or projecting` therethrough, with theinternally threaded passage 30, thereof communicating with the passage31, of said discharge arm. The outer and inner ends of said Valve tube29, are externally threaded. Adjustably threaded within the passage 30,is a threaded shank or screw portion 32, haring integrally formed on oneend thereof an actuating roc 33, which projects outwardly through anapertured cap 34, removably threaded upon the externally threaded outerend of the valve tube 29. Disposed within the cap 3l, is a packing 35,and a washer 3G, adapted to afford a tight joint around the valve rod33. The outer end of the ralye rod 33, is squared as denoted by thereference numeral 37, to permit a wrench or other suitable tool to beapplied thereto to rotate the Valve rod. lntegrally formed on the otherend of the threaded shank 32, is a valve stein 33, of reduced diameter,which projects longitudinally through the passage 30, and has the outeror projecting end thereof reduced and chainfered on one side only asdenoted by the reference numeral 39, to form a needle valve point 4 0.The chainfered needle valve point 40, adj ustably projects through anoutlet opening formed centrally in a nut cap 4:1, which is removablythreaded on the inner end of the valve tube Q9, and has a cylindricalportion 4t2, thereof projecting through the opening provided for thepurpose in the end wall of the shield 27. The valve needle 40, ischainfered or beveled to afford a means for regulating the valve outlet,by rotation of the ralve rod To start the process of oil-gas generationa starting burner is positioned below the generating pipe 23. Thestarting burner comprises an open trough gt3, supported at one end by abracket 44, attached to the bottoni of the generating burner 16. Theother end ot the trough e3, is attached to the bracket arin 2G. A wick45, is placed longitudinally within the open trough 43, and is saturatedwith kerosene or any other suitable oil from below by means of an underfeed neck or sleeve 4G, which projects outwardly from the central frontportion of the trough. 'l1 he outer open end of the under feed sleeve4G, is removably plugged or closed by a screw et?, to permit cleaning ofthe passage leading into the trough. A vertical priming or feed pipe a8,is threaded into an opening pro- `vided in the top of the sleeve a6, topermit small quantities of kerosene oil to be poured therein. The oilentering the pipe 48, of course flows through the passage in the sleeve4G, and into the lower portion of the trough to saturate the wick 45,from below.

The operation is as follows:

To start the process` of oil-gas generation kerosene oil or alcohol ispoured into the iniming pipo 48, and liows through the sleeve 4:6, intothe trough 41:3, of the starting burner to saturate the wick 45. rllhesaturated wick is lighted and the heat resulting from the burning wickacts to rapidly heat the generating pipe 23, disposed above the startingburner. Kerosene or any other suitable hydro-carbon fuel is supplied tothe inclined generating pipe 23, through the main supply pipe 25, andthe intake arm 2li. ils clearly shown the ,generating or Vaporizing pipe28, is inclined downwardly toward its inlet end, thereby preventing anyimpurities, foreign matter or carbon contained in the oil from enteringthe device. As the intake arm 2li, fills with kerosene small quantitiesthereof gradually flow into the heated pipe 23, the heat from thestarting burner acting to vaporize the oil to form a gas which passesthrough the generating pipe 23, and the discharge arm 22, into thepassage 30, of the valve mechanism. The valve rod 33, is rotated toretract or draw the valve stem 3S, inwardly, thereby causing thechainfered valve needle 4i-O, to also move inwardly to open the valveoutlet in the cap end 42, permitting the vaporized oil to passoutwardly.

The draft caused by the air flowing into the carbureting tube l2, andupwardly through the casings 7 and l, acts to draw the escapingvaporized oil from the valve mechanism. into the carbureting tube. Thean: in the tube 12, isv thus carbureted with the vaporized oil to' forman oil-gas, which, of course, flows through the opening 8, into theauxiliary casing 7, and upwardly through the opening l0, into the casingl. The oil-gas from the casing l, is permitted to escape through thecooking burner apertures 5. The escaping oil-gas is lighted andfurnishes a very hot flame suitable for cooking purposes. Some of thegenerated eil-gas from the casing l, flows through the opening Q, intothe generating burner lf3-17, and out through the apertures 1S and 19.rlhe escaping oil-gas from the generating burner is lighted and theresulting flames engage the generating pipe 23 and the discharge arm 22,thereof, as well as the valve mechanism disposed within the shield 27,which acts to direct the llames from the burner apertures 19, around thevalve tube 29, to heat the valve parts to prevent the vaporized oiltherein from cooling before it is mixed with air in the carbureting tubel2. The process of oil-gas" generation is thus continued, after oncebeing started by the starting burner, which of course goes out after thekerosene with which the wick 45, is saturated has burned up.

lVhen it is desired to shut off the burner the supply of oil from thetube 25, is closed by any suitable valve positioned in the .main feedpipe. rlhe cooking burners and the generating burner are then allowed toburn until all of the oil-gas fuel in the casings 7 and l, as used up.

The inclined position of the generating pipe Q3, acts to preventcarbonization of the various parts of the generator and burner, andfurther permits any impurities which may have collected in the lowerportion of the intake arm 24, to be drawn olf by removing the closurenut 49, which connects the tubes 25, to the arm 2i. The under feedarrangement of the starting burner permits additional quantities ofprimingl oil to be poured into the pipe 18, while the wick 45, isburning, in case the device does not get properly started by a singlesaturation of the wick. The pouring of oil on top of the wick e5, whenthe same is burning of course is very dangerous, and the under feedarrangement affords a safe means for properly starting the process ofoil-gas generation.

The removal of the valve caps 34 and 41, permits proper cleaning of thevalve mechanism. The sleeve 46, of the starting burner may also becleaned by removing the screw al?.

I am aware that numerous details of construction may loe varied througha wide range without departing from the principles of this invention,and I therefore do not purpose limiting the patent granted otherwisethan necessitated by the prior art.
